| Abstract: | Some chief construction techniques currently used for building highway tunnels in weak surrounding rocks are discussed in this paper.Numerical analyses were carried out to analyze the construction mechanics of bench excavation method,CD and CRD excavation method.The mechanical characteristics and defects of these methods were considered.Some useful suggestions are put forward for tunnels constructed in weak surrounding rocks. |
